Lifetime risk of stress urinary incontinence or pelvic organ prolapse surgery.

OBJECTIVE: To estimate the lifetime risk of stress urinary incontinence (SUI) surgery, pelvic organ prolapse (POP) surgery, or both using current, population-based surgical rates from 2007 to 2011.

METHODS: We used a 2007-2011 U.S. claims and encounters database. We included women aged 18-89 years and estimated age-specific incidence rates and cumulative incidence (lifetime risk) of SUI surgery, POP surgery, and either incontinence or prolapse surgery with 95% confidence intervals (CIs). We estimated lifetime risk until the age of 80 years to be consistent with prior studies.

RESULTS: From 2007 to 2011, we evaluated 10,177,480 adult women who were followed for 24,979,447 person-years. Among these women, we identified 65,397 incident, or first, SUI and 57,755 incident prolapse surgeries. Overall, we found that the lifetime risk of any primary surgery for SUI or POP was 20.0% (95% CI 19.9-20.2) by the age of 80 years. Separately, the cumulative risk for SUI surgery was 13.6% (95% CI 13.5-13.7) and that for POP surgery was 12.6% (95% CI 12.4-2.7). For age-specific annual risk, SUI demonstrated a bimodal peak at age 46 years and then again at age 70-71 years with annual risks of 3.8 and 3.9 per 1,000 women, respectively. For POP, the risk increased progressively until ages 71 and 73 years when the annual risk was 4.3 per 1,000 women.

CONCLUSION: Based on a U.S. claims and encounters database, the estimated lifetime risk of surgery for either SUI or POP in women is 20.0% by the age of 80 years.
